. In general, the

invention consists ina dyeing-Vessel or kier of anysuitable form hav-` 1929. Serial No. 381,505.

ing inlet and exhaust pipes for circulating the dye liquor orother Huid through the material to be treated and provided with an interior holder or carrier for supporting the material in the kier in a mass surrounding a perforated standpipe, with the carrier adapted-toy be lifted out from the kier to remove the material therefrom. A particular feature of the invention consists in means for automatically connecting the standpipe f the carrier with the intake pipe .of the kier to vsecure a fluid-tight joint therebetween and a further feature comprises means for dividing the mass of material surrounding the standpipe in twoV or more separate sections whereby it may be readily removed from the holderor carrier after the latter has been withdrawn from the kier.

The present invention may be .applied to i practically any type of dyeing-vessel, but as herein illustrated it is adapted for use with a cylindrical kier or vat such as shown in yvertical staves 4 which are bound together by means of suitablewire hoops 5.' Abutting the lower ends of the staves 4 is a fiatA ring or annulus 6 which serves as the anchoring means for a series of vertical tie-rods 7. Surrounding the upper portion of the kier is a metal band or hoop 10 bolted to the staves 4 at 11. The vertical tie-rods 7 are inserted through holes 12 in the lower annulus 6 and secured thereto by units 13 with their upper ends screwed into threaded-holes in the band or hoop '10. -v

-A cover 15 seats across the top of the kier 2 with a gasket 16 arranged therebetween to provide a Huid-tight joint. rlhe cover 15 is clamped down a ainst the top of the kier by means of bolts 1% hoop or band 10. The bolts 17 are swung on their pivots. to eng-age them with slots pivotedto ears 18 on the` the'. drawings and designated generally by A i in the edge of the cover 15 and suitable nuts A the top of thekier. A reeriforcing frame 20 l of angle-irons braces the top of the cover` 15 with the flanges ofthe latter slotted to receive the clamping bolts' 17. The cover 15 is further braced by truss-rods 21 extending radially from the angle-irons of the frame to a central support 22 constructed with a vertical tubular stem 23. A bolt 24 extends through the top of the stem 23 and carries a shackle-eye 25 which is employed in placing .the cover o-n and lifting it off from the kier The cover 15 may be provided with the usual Y testing instrumentsand appurtenances such 25' as a pressure-gauge 31, thermometer 32 and a hand-hole cover 33 for sampling the batch as it is -dryed or treated in the kier. These partsof the apparatus are ynot essential to the present invention, however, and are therefore not described in detail. l

As shown in Fig. 1, the kier 2 is preferably supported in raised position above the floor by means of a foundation of cement blocks or the like as indicated `at 34. Opening through the center of the bottom of the kier is an intake-pipe 35 havingY its iiange bolted to an annular plate 36 resting on the floor of the.

kier and formed with a' raised seat-ring 37,

1 see Fig. 4. An' exhaust-pipe 38 leads from an opening 39 at one side of the inlet "opening 40, being secured in place by bolts .41 anchored in a ring 42 let into the floor of the l kier. The intake or feed-pipe 35 leads from a suitable pump connectedwithA an expansiontank and the exhaust-pipe 38 leads back tothe tank with suitable valves for regulating thel flow of the liquid to and from the kier, thearrangement of these parts being as usually employed and therefore not herein illustrated. v0n the lfloor of the kier 2 is a circular rail or ring 43 disposed adjacent the staves 4 and adapted to support a'spider 44 constituting the bottom of the holder or carrier for the material which is indicated generally at 45. Referring more particularly to Figs. fand 2, a pair of vertical angle-irons 46 are arranged in diametrically opposite relation onv the interior ofthe barrel of the kier, being i fastened to its sides by means of screws 47.

The angle-irons 46 serve as tracks for guiding v the carrier into and outI from the interior of the kier in the manner as later more fully explained.

The material holder or carrier 45, shownin perspective view in Fig. 3, comprises the lower spider 44 which is preferably constructed with acentral hub 50 and radial arms y 51 connected at their outer ends by a circular rib 52, see Fig. 2. The hub 50 of the spider or grid 44 has an axial hole in which is seated a vert-ical standpipe 55 having perforations 56 in its sides for the passage of the dye liquor or other fluid. Referring to Fig.v 1, the standpipe 55 is held in place in the bore of the hub 50 by means of a ring 57 screwed onto its lower end and fastened in a counterbore in the hub by means of screws 58. In the underside of the hub 50 is an annular groove forming a seat for a gasket or washer 60 which rests against the raised seat-ring 37 on the plate 36 fastened to the floor of the kier. The hydraulic pressure of the fluid against the material supported on the holder or carrier 45 causes the gasket 60 to be compressed between the hub 50 and t-he seat-ring 37 to effect a fluid-tight joint at this point in the manner as later explained. It will be under-l stood that the liquid flowing into the kier capes through the perforations 56 in the pipe. I

rPhe outer ends of the arms or ribs 51 of the spider 44 rest on the rail or ring 43 to support the main weight of the carrier 45 and the material contained thereon.

Resting across the top of the spider 44 is a perforated plate 61 which is preferably secured in place by screws or rivets 62 fastened in holes in the arms 51, see Fig. 2. The plate 61 is provided with slots 63 in its periphery to adapt it to slide down on the vertical angleirons or guiding-tracks 46.

As shown most clearly in Fig. 3, the material carrier 45 is provided with a vertical plate 65 which divides its bottom plate 61 into two halves and extends nearly to the top of the standpipe 55. The plate 65 serves as a separator for dividing the mass of material carried on the carrier into two sections and, if desired, further radial plates may be employed to separate `the mass into small segments. As hereinillustrated, the separatorlplate 65 comprises two portions extending diametrically of the standpipe 55 and fastened thereto by means -of semi-circular clamps 66 riveted to the plate and the pipe.

The separator-plate 65 is also fastened to the bottom plate ',.61 by means of angle-shaped gussetsl or clamps 67` riveted thereto. At the top of the standpipe 55 is a cross-bolt 68 to which is attached a shackle-eye 70.

The screen-grid or compression-plate 30 which is placed on top'of the mass of material held on the carrier 45 is preferably formed in twohalves as shown in Fig.,2. The screengridkmay comprise two sections, each havingy a framework-71 formed from a metal rod bent Vto-conform to one-half of the interior. of the kier and extending diametrically thereacross withits center bowed outwardly at 73 r to encircle the standpipe 55. Stretched across the framework 71 is a screen 74 of relatively heavy wire mesh. A suitable hand-hole :75 bound with a ring 76 is made in one of the sections of the screen-grid 30 to adapt it to register with the hand-hole through the cover 15 as shown in Fig. 1.

Having now described the construction and arrangement of the improved apparatus in detail, its method of operation will next be explained. lith the cover 15 removed from the kier and the carrier or holder in place therewithin the librous'material is dumped onto the lower plate 61 and packed closely around the stand-pipe 55 clear to thetop clamped against the top of the kier by means of the bolts 17 and nuts 19. As the cover is clamped down into place the slats 28 on its underside will bear against the rim of the screen-grid 30 to force the latter down against the material to compress it into `a relatively dense mass andthe batch is then ready for treatment with the dye liquor or other fluid.

rlhe pump is startedand the valves manipulated to cause the iiuid to flow through the intake-pipe 35 and inlet 40 up into the standpipe 55, from which it is forced radially outwardly through the perforations 56-to penetrate the mass surrounding the standpipe.

It is to be particularly noted that the standpipe 55 is Open at 'the top *and that therefore the fluid will flow therefromxinto the upper part of the kier where it creates hydraulic y pressure against the mass of material on the carrier 45. 'YIhis pressure is exerted against the carrier toforce the hub of the spider 44 down toward the bottom of the kier to compress the gasket 60 against the seat-ring 37,

whereby to seal the joint at the intake-pipe 35. In this way the standpipe is automatiy cally connected to the intake-pipe .35 with a fluid-tight joint so as to obviatethe necessity for manually coupling the parts together.

The fluid circulated through the system permeates the mass-both from the top and radially from its center, draining down through the perforated bottom plate 61 intoy the bottom i of the kier, whence it is exhausted through the dyed throughout with an even color.l After the dying operation the batch may be washed by circulatingwater through the kier in the same manner.`

After the treating process is completed the cover 15 is lifted oil from the top of the kier 2 and the screen-grid 30 removed from the top of the mass.vv A suitable tackle or chain-hoist is then hooked into the shackle-eye and the holder or carrier 45 is hoisted out from the kier with the treated material contained thereon in a solid mass. After the carrier has ybeen withdrawn from'the kier the mass of treated material surrounding-the standpipe 55 maybe readily removed in two halves without theV fibers clinging and binding around the pipe. The mass being separated into two halves, each section is easily drawn off from the bottom plate 61 and;away from sof the standpipe 55 without the necessity of breaking it up or lifting the whole mass bodily upward. In this way considerable time and labor is saved and the mass of material is so divided as to be in more convenient form for transfer to further processes. I-Ieretofore, where it has been necessary to lift the wholermass off from the bottom of the kier or from a carrier held therein, considerable difficulty has been experienced in separating it from the standpipe. With the 4present apparatus the ymass of fibers is parted so that each half may be readily withdrawn and thereby the operation of removing the material from the kier is expedited and rendered more convenient.

While we have herein described and illustrated the invention as embodied in a preferred type of apparatus, ,it is to be understood that various modifications may be made in the construction and arrangement of the machine without departing from the spirit or scope of the invention.A Therefore, without V'limiting ourselves to the precise con-v struction shown anddescribed, we claim:
